Multiphase procedure for landscape reconstruction and their evolution analysis. GIS modelling for areas exposed to high volcanic risk
This paper – focussed on the province of Naples, where many municipalities with a huge demographic and
building density are subject to high volcanic risk owing to the presence of the Campi Flegrei (Phlegrean
Fields) caldera and the Somma-Vesuvius complex – highlights the methodological-applicative steps leading
to the setting up of a multiphase procedure for landscape reconstruction and their evolution analysis.
From the operational point of view, the research led to the: (1) digitalisation, georeferencing and comparison
of cartographies of different periods of time and recent satellite images; (2) elaboration and publication
of a multilayer Story Map; (3) accurate vectorisation of the data of the buildings, for each period of time
considered, and the use of kernel density in 2D and 3D; (4) application of the extrusion techniques to the
physical aspects and anthropic structures; (5) production of 4D animations and film clips for each period of
time considered. A procedure is thus tested made up of preparatory sequences, leading to a GIS modelling
aimed at highlighting and quantifying significant problem areas and high exposure situations and at reconstructing
the phases which in time have brought about an intense and widespread growth process of the artificial
surfaces, considerably altering the features of the landscape and noticeably showing up the risk values.
In a context characterised by land use conflicts and anomalous conditions of anthropic congestion, a
diagnostic approach through images in 2D, 3D and 4D is used, with the aim to support the prevention and
planning of emergencies, process damage scenarios and identify the main intervention orders, raise awareness
and educate to risk, making an impact on the collective imagination through the enhancement of specific
geotechnological functionalities of great didactic interest
Septic emboli secondary to Infective Endocarditis
A 31 year old lady was brought to casualty by a friend, unconscious and incontinent of urine and faeces. She was responsive
to verbal stimuli with a Glasgow Come Scale (GCS) of 10 and noted to have a fever of 39.6oC. She had a blood pressure (BP) of
116/65 mmHg and a pulse rate of 160 bpm. She was allegedly unresponsive for two days prior to admission. She is a known
intravenous drug user (IVDU). Physical examination revealed bilateral puncture wounds in the groin. In view of her poor general
condition she was admitted to the intensive therapy unit (ITU). She was started in empirical antibiotics which included both G+ and
G- coverage. Blood culture eventually grew a methicillin sensitive staphylococcus areus (MSSA), and the antibiotics were eventually
downgraded to flucloxacillin. A transoesophageal echocardiogram (TOE) showed a massive infective endocarditis of the mitral valve,
which was rendered incompetent. An MRI scan of the brain revealed multiple septic emboli resulting in several cerebral infarcts.peer-reviewe
3D and 4D Simulations for Landscape Reconstruction and Damage Scenarios. GIS Pilot Applications
The project 3D and 4D Simulations for Landscape Reconstruction and Damage Scenarios: GIS Pilot
Applications has been devised with the intention to deal with the demand for research, innovation and
applicative methodology on the part of the international programme, requiring concrete results to
increase the capacity to know, anticipate and respond to a natural disaster. This project therefore sets
out to develop an experimental methodology, a wide geodatabase, a connected performant GIS
platform and multifunctional scenarios able to profitably relate the added values deriving from
different geotechnologies, aimed at a series of crucial steps regarding landscape reconstruction, event
simulation, damage evaluation, emergency management, multi-temporal analysis. The Vesuvius area
has been chosen for the pilot application owing to such an impressive number of people and buildings subject to volcanic risk that one could speak in terms of a possible national disaster. The steps of the
project move around the following core elements: creation of models that reproduce the territorial and
anthropic structure of the past periods, and reconstruction of the urbanized area, with temporal
distinctions; three-dimensional representation of the Vesuvius area in terms of infrastructuralresidential
aspects; GIS simulation of the expected event; first examination of the healthcareepidemiological
consequences; educational proposals. This paper represents a proactive contribution
which describes the aims of the project, the steps which constitute a set of specific procedures for the
methodology which we are experimenting, and some thoughts regarding the geodatabase useful to
“package” illustrative elaborations. Since the involvement of the population and adequate hazard
preparedness are very important aspects, some educational and communicational considerations are
presented in connection with the use of geotechnologies to promote the knowledge of risk
Uniqueness of solutions of the stochastic Navier-Stokes equation with invariant measure given by the enstrophy
A stochastic Navier-Stokes equation with space-time Gaussian white noise is
considered, having as infinitesimal invariant measure a Gaussian measure
\mu_{\nu} whose covariance is given in terms of the enstrophy. Pathwise
uniqueness for \mu_{\nu}-a.e. initial velocity is proven for solutions having
\mu_{\nu} as invariant measure.Comment: Published by the Institute of Mathematical Statistics
